Has anyone out there installed Win XP 64 with this MB? When I\ninstalled the OS, ieverything went well up until the first reboot.\nRebooted OK until the final screen. Screen went black, but monitor was\nstill showing video present. System will boot in safe mode. I am using\nthe Asus AX700 Pro Video card and I suspect that it is the culprit.\nHowever I haven't found any way to get around the problem because the\nsystem behaves the same way after I install the AX700 64 bit driver.\nWhen installing Win XP (32bit ) no problems.\nAnyone have any suggestions or comments.\n\nAlso it shows in the P5AD2- E manual addendum a option to enable the\nSpeedStep (EIST) feature. I have installed the latest Bioes and this\nis still not present. What gives?\nJohn L.
